Built from solid carbide and coated with TiAlN (TiN at the tip) for extended tool life, it features a 140-degree standard point angle that supports accurate entry and reduced thrust. The bit measures 2.5984 inches overall length with a 0.1660 inch (Size 19 wire gauge) cutting diameter and a 0.2362 inch straight cylindrical shank. Its stub-length configuration provides added rigidity, making it well-suited for CNC screw machines, machining centers, and drill presses where deflection control is critical. Coolant-through capability supports chip evacuation and thermal management during deep cuts.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for professional machinists and toolroom technicians working in manufacturing, aerospace, automotive, and general metalworking environments. The stub-length design limits overhang and improves concentricity in short-reach drilling operations. The 2-flute regular spiral geometry handles a wide range of workpiece materials. Maximum drilling depth is 0.6693 inches (17.00 mm), making it appropriate for through-hole and shallow blind-hole applications at tight tolerances. The DIN 6537K specification ensures dimensional consistency for repeatable setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior hardness and wear resistance compared to HSS tooling\u003c\/li\u003e\n\u003cli\u003eTiAlN multilayer coating with TiN tip for heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e140-degree standard point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip evacuation and controls heat in demanding cuts\u003c\/li\u003e\n\u003cli\u003eStub-length body increases rigidity and minimizes deflection in short-reach setups\u003c\/li\u003e\n\u003cli\u003eTapered web configuration reinforces the cutting edge across the flute length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for screw machines, CNC machining centers, and drill presses accepting a 0.2362 inch straight cylindrical shank in the Size 19 wire gauge drill class.

Verify chuck or collet size matches the 0.2362 inch shank before seating the bit. Coolant-through setups require that the coolant supply line is connected and pressure-tested before initiating a drilling cycle. Avoid exceeding the maximum drilling depth of 0.6693 inches in a single pass without adequate chip clearance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 19\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1660 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN Multilayer \/ TiN (Tip)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.9449 inches (24.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5984 inches (66.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 inches (6.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (36.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.6693 inches (17.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: B051A-CPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4151122\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739374551346,"sku":"4151122","price":124.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d81dabe9b1c47df0bc5f705b9b2685d9.jpg?v=1788813754","url":"https:\/\/voomisupply.com\/products\/kennametal-4151122-drill-bit-size-19-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
